We divide 80018960 by 804
The aim is to understand the frequency of 804 in 80018960.

Moving on to step 1:
The number 804 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 804

Let's proceed to step 2:
When dividing 80 by 804, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 804

On to step 3:
804 goes into 800 0 times with a remainder of 800.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 800 and we're left with 800.
Bring next digit (1) of the dividend behind the 800 and repeat the process: 8001 / 804

Moving on to step 4:
8001 divided by 804 is 9 with a remainder of 765.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 7236 away from 8001, we end up with 765.
Take the next digit (8) from the dividend and append it to 765, then repeat: 7658 / 804

Going ahead to step 5:
7658 divided by 804 is 9 with a remainder of 422.
Put 9 as the next digit of the answer. 
Result so far: 99.0
The remainder is 422 after subtracting 7236 from 7658.
Bring next digit (9) of the dividend behind the 422 and repeat the process: 4229 / 804

On to step 6:
804 goes into 4229 5 times with a remainder of 209.
Record the quotient 5 as the next digit in the result. 
Result so far: 995.0
If we take 4020 away from 4229, we end up with 209.
Take the next digit (6) from the dividend and append it to 209, then repeat: 2096 / 804

Step 7:
804 can be fit into 2096 2 times, resulting in a remainder of 488.
Put 2 as the next digit of the answer. 
Result so far: 9952.0
If we subtract 1608 from 2096, we get 488.
Bring next digit (0) of the dividend behind the 488 and repeat the process: 4880 / 804

Step 8:
4880 divided by 804 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 99526.0
If we subtract 4824 from 4880, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
804 goes into 560 0 times with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 99526.0
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 10:
If we divide 5600 by 804, we get 6 and a remainder of 776.
Use 6 as the next digit of our solution. 
Result so far: 99526.06
Deduct 4824 from 5600 and we're left with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

On to step 11:
804 goes into 7760 9 times with a remainder of 524.
The next digit of our result is 9. 
Result so far: 99526.069
Subtracting 7236 from 7760 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 12:
5240 divided by 804 is 6 with a remainder of 416.
The number 6 becomes the next digit in our result. 
Result so far: 99526.0696
If we take 4824 away from 5240, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 13:
4160 divided by 804 is 5 with a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 99526.06965
Deduct 4020 from 4160 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 14:
1400 divided by 804 is 1 with a remainder of 596.
Use 1 as the next digit of our solution. 
Result so far: 99526.069651
The remainder is 596 after subtracting 804 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 15:
The number 804 fits into 5960 7 times, leaving a remainder of 332.
Use 7 as the next digit of our solution. 
Result so far: 99526.0696517
Deduct 5628 from 5960 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 16:
3320 divided by 804 is 4 with a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 99526.06965174
If we subtract 3216 from 3320, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 99526.06965174, and the remainder is 1.04e-07.
